晚上有应用人员说测试库连不了,第一反应是看看/oracle文件系统是否满了,没满,于是再看看alert文件,一堆报错
Errors in file /oracle/app/admin/crmkfdb/bdump/crmkfdb_psp0_152212.trc:
ORA-27300: OS system dependent operation:fork failed with status: 12
ORA-27301: OS failure message: Not enough space
ORA-27302: failure occurred at: skgpspawn3
最后库库down了,一看skgpspawn3,肯定是交换空间的问题了,再看看alert文件开始报错的时间,正好和主机交换空间被应用程序耗光的时候,于是起了库,再查查metalink有什么新东西。
This note helps identify the possible causes of the ORA-2730x errors that have already been reported and provides solution where available. The errors are usually caused by OS system call error or OS configuration issue and are in the form. of:
ORA-27300: OS system dependent operation:%s failed with status: %s
ORA-27301: OS failure message: %s
ORA-27302: failure occurred at: %s
Documentation is available at the OS level for some of the dependent operation or OS calls such as fork() or semget(). The 'status' reported in the ORA-27300 error usually corresponds to a Unix error code defined in the "errno.h" header file on the OS, returned by the OS call.
For example,
ORA-27300: OS system dependent operation:fork failed with status: 11
A "man fork" shows:
The fork() function shall fail if:
EAGAIN (status 11) : The system lacked the necessary resources to create another process, or the system-imposed limit on the total number of processes under execution system-wide or by a single user {CHILD_MAX} would be exceeded. EAGAIN corresponds to status 11.
The fork() function may fail if:
ENOMEM (status 12) : Insufficient storage space is available.
Troubleshooting Details
The note is broken down by the status code.
